' STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 660,145, dated October 23, 1900. Application filed May 12,1900; Serial No. 16,481. No model.)

To t whom, it may concern:

Be it known that I, FRANK JOZEF CHAM- RoD, a citizen of the United States, residing at Lima, in the county of Allen and State of- Ohio, have invented a new and useful Steam- 'by the circulation of the water may be controlled or regulated; and a still further object is to provide the boiler with animproved mud- (lrum. a

With these objects in View myinvention consists in the improved construction and novel arrangement of the parts of a steamboiler,-as will be hereinafter more fully set forth.

In the accompanying drawings, in which the same numerals indicate corresponding parts in each of the views in which they occur, Figure 1 is a longitudinal sectional view, partially in elevation, of a steam-boiler provided with my improvements. Fig. 2 is a front elevation, partly in cross-section, of the same. Fig. 3 is a similar rear view; and Figs. 4 and 5 are longitudinal, sectional, and front elevations, respectively, of one end of a flue provided with my improved regulator.

Referring more particularly to the drawings, 1 indicates the main portion of an ordinary boiler, which may be provided with outside or inside firing, as the case may be. The boiler is provided with the usual circulatingtlues 2 and may have plain or corrugated fire-boxes 3, which may be located on the interior of the shell or the exterior, or both, in the well-known manner. The rear end of the boiler will be provided with a self-supporting head 4, with a face joined like a cylinderhead, by means of which the boiler can be very readily opened for the purpose of being cleaned out or repaired.

The sides of the rear end,of the boiler are tapered toward each other, as shown at 5, at the upperportion of which is secured the rear end of the usual cylindrical portion or steamdrum 6 of the boiler. The front end of the cylindrical portion is supported by'the usual hollow standard '7, from which extends one or more branch pipes 8, which communicate with the lower forward portion of the boiler through the pipe 9.

Instead of providing the boiler With the usual mud-drum I prefer to locate the drum 10 upon the outside of the furnace-wall, so that the water in passing from the upper to the lower portion of the boiler at the front end will be forced to pass through the drum.

I The drum is provided with two cones l1 and ven ted from returning, thereby assisting very materially in purifying the water. The drum is provided with the usual manhole 13 and blow-oif pipe 14: for cleansing it. at any time. The branch pipe 9 is connected to the upper end of the drum, and the pipe 8 leads from the side of the drum,'near the top, directly to the boiler.

In one end of the fiues 2 I prefer to insert a regulator, which consists of a cylindrical cup-shaped body 15 of a less diameter than the flues and having radial wings 16, which are of sufficient width to fit snugly within the fines and extend longitudinally of the body a sufficient distance to give the regulator a firm and rigid support. The outer end of each of the wings is provided with a head or shoulder 17, which engages with the end of the flue and prevents the regulator being inserted too far. If it should be found that the insertion of a solid regulator would obstruct the passage of the water to too great an extent, it could be provided with a perforation or opening at its center, as shown in dotted lines at 18. When constructed in this manner, it will be evident that my improved boiler will have all of its parts so arranged as to be ready of access for the purpose of repair or cleansing and that the water willhave free circulation, so as to utilize the heat from the fuel to the greatest extent. In its circu lation from the inclined fines in the main portion up to and through the cylindrical portion at the top and from thence down at the sides of the fire-boxes into the lower portion of the boiler it will be assisted by the heat from the boiler in one direction and by gravity upon the cooler water in the other direction, and the cooler portion of the water will pass through the mud-drum, where the greatest 1 amount of precipitation of sediment of foreign substances will take place.

The boiler can be used for stationary or ma:

rine purposes, and the steam-drum has a'wator-separator and a steam-separator below the outlet and has a manhole in the side of the shell. In the drawings I haveonily shown the arrangement of the circulating-pipes for a single boiler; but it will be readily understood that if there shouldbe more than. one boiler in the battery the circulation would what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a steam-boiler, the combination,with

the main portion, the rear end of which is provided with a self-supportinghead, joined thereto in the manner of a cylinder-head, of a steam-drum connected to the rear end thereof, and a branch pipe communicating with the front end of the drum and with the lower forward end of the boiler, substantially as described.

2. In a steam-boiler, the combination,with the main portion, of a steam-drum connected with the rear end thereof, a branch pipe communicatingwith the forward end of the drum, a mud-drum commutricating with the lower end of said pipe, and a pipe leading from the upper end of the mud-drum to the bottom of the boiler, substantially as described.

3. In a steam-boiler, the combinati0n,with the main; portion thereof, of a steam-drum connected with the rear end of the main portion, a branch pipe communicating with the "forward end of said drum, a mud-drum con nected with thelower end of the branch pipe, said mud drum being provided with two bones, the upper one of which is inverted i and provided with an opening directly above the apex of the other one, and a pipe leading from the upper end of the mud-drum to the boiler, substantially as described.

4. In, a steam boiler, the combin-ation,with the main portion provided with heat-circulating flues,,ol aregulator in the forward end a of each of said fines, a steam-drum connected with the rear end of the main portion of the boiler, and a branch pipe communicating with the forward end of the steam-dru m and with the boiler,substantially as described.

5. In a steam -boiler, the combination,with

the main portion provided with circulatingflues, of a regulator in each of said lines, each of said regulators consisting of a cylindrical body of less diameter than the lines,

,rad'ial wings upon said body of a sulficient Width to engage withthe interior of therflues,

and the outer end of each wing being'pro- 'vided with a shoulder, a steam-drum connected with rear end of the main portion, and a. branch pipe communicating with the forward end of the drum and with the boiler, substantially as described.
